SPECIFICATION forming part of Letters Patent No. 623,564, dated April25, 1895 Application filed January 20, 1899. Serial No. 702,793. (Nomodel.)

To all whom, it may concern:

Be it known that we, MARSHALL SATTLEY and AROHIBALD SATTLEY, ofSpringfield, in the county of Sangamon and State of Illinois, haveinvented certain new and useful Improvements in. Cultivators, of whichthe following is a specification.

In a general sense this invention relates to convertible riding orwalking cultivators, though some of the details are capable ofapplication to non convertible cultivators as well. It is exemplified inthe structure hereinafter described, and it is definedin the appendedclaims.

In the drawings forming part of this specification, Figure l is a planof so much of a cultivator as is needed to illustrate our improvementswith the parts placed in proper corelation for the operator to ride.Fig. 2 is a similar View. with the parts shifted to convert the deviceinto a walking-cultivator. Fig. 3 is an elevation corresponding with theplan shown in Fig. 1. Fig. 4 is an elevation corresponding with the planshown in Fig. 2. Fig.

2 5 5 is a front elevation of the front orhitch arch,

showing details of the means used to neutralize a part of the weight ofthe shovel-beams. Fig. 6 is an enlarged detail, inside elevation, of theweight neutralizing spring and adj uncts thereof. Fig. 7 is a detail inside elevation of the means employed to hold the seat at differentheights, such elevation being taken on broken line x in Fig. 1. Fig. 8is a plan illustrating a modified form of telescopic or extensible endcontractible frame. Fig. 9 is a section on broken line a: in Fig. 8.

The structures delineated in the drawings and hereinafter particularlydescribed are embodiments merely of our ideas. They show one way inwhich the invention may be put into practical use, but they are intendedto be illustrative not restrictive. They give an instance of theconditions set forth in the claims, but it is obvious that suchconditions may be exemplified by structures somewhat different in manyways from those shown. In this particular instance the invention isembodied in a cultivator made as follows, namely: An arched axle 1 ismade in the form usual in straddle-row cultivators and is promeans ofbrackets l.

vided with carrying-wheels 2 and 2. A pair of angle-bars 3 are laidcrosswise of the axle, parallel one to the other, one on each side ofthe center of the axle and equidistant therefrom, and they are fastenedto the axle by (Seen only in the elevations.) The forward ends of theangle-bars converge to the tongue 4,with which they connect, and theirrear ends terminate to the rear of the axle. A cross-bar 5 connects theangle-bars together slightly to the rear of the bends thereof, andoblique braces 32 extend from the conjunction of the cross-bar with theangle-bars to the lower parts of the vertical extensions of the axle.The rear end of the tongue connects with the cross-bar 5, and adraft-bar 6 is connected with the tongue in the customary manner. Thesefeatures constitute the carrying-frame or as much thereof as is neededto explain our invention, and on this frame the cultivating mechanism ismounted slidably, the means employed in this instance being as follows:A pair of slides 7 are mounted one on each of the angle-bars 3, and tothe front ends of the slides is connected an arched bar or shaft 8.-This bar crosses the slides and extends laterally beyond the same onboth sides. Then'ce it extends downward, as shown at S, and from thelower ends of the vertical extensions it turns inward, as shown at 8",and provides horizontal bearings for the beamcouplings. The arch-bar Sis held in an approximately vertical position by braces 24, which extendupward and backward from the inner ends of horizontal extensions 8 andconnect with the slides in the rear of archaxle 1. Between the ends ofthe slides and at the inner edges thereof are lugs 25, and the frontends of seat-bars 26 are connected pivotally with these lugs.Stud-brackets 28 extend from the converging parts 3 of the angle-bars 3,and bars 29 connect pivotally with the studs and also connect pivotallywith the seat-bars at 30. The seat-bars extend parallel with the slidesfor some distance to the rear of the arch-axle and then converge to forma support for seat 27. Dhey are pro vided at 31 with swingablerest-blocks which are adapted to engage the axle and vary the height ofthe seat. The details of construction of the rest-blocks willhereinafter appear. Brackets are fastened to the rear ends of slides 7.They are provided with ratchet-racks 17 of are formation, and theyfurnish pivotal bearings for the lower ends of the lock-levers 16. Hooks18 are pivoted onto the lock-levers, above the pivots thereof, andchains 20 extend from the hooks around bearings 19' on the forwardarch'bar 8 and connect with the cultivator-beams 12, to the rear of thecouplings thereof. The connection of the chains with the beams is madethrough short stubby springs, as 21, and rods, as 22, connecting thesprings with eyes 23 on the beams. The beams have laterally-swin gablehandles, as 13, and stirrups or foot-rests 14, as shown in Fig. 1, andthey connect with the horizontal extensions 8 of arch-bar S by means ofthe coupling members 10 11 and sleeves f). The sleeves fit looselyon theextensions, thereby furnishing vertical play for the beams, and member11 of the coupling swings horizontally on member 10 or 011 the pinthereof.

The sleeves 9 have arms 33 extending upward, and forward-extending heads33 are formed on the upper ends of the arms. Extension-springs 31 areconnected at their upper ends with the heads of the arms and at theirlower ends with downward and forward extensions 21 of the brace-bars 2%.Links 35 connect the springs with the extension 24:, and a set ofrecesses at varying distances from the axes of sleeves 9 are formed inthe extension to receive the link. This provides one means forregulating the tension of the springs and other means resides in thethreaded bolt 36, which engages the upper end of the spring and extendsthrough the head of arm and the nut 37 on such threaded bolt. (See Fig.6.)

The rest-block 31 is shown in detail in Fig. 7,- and its leadingcharacteristic is the set of bearing-surfaces 31 at different distancesfrom its pivot. These bearing-surfaces are adapted to rest on the archedaxle 1 and support the seat at different heights; but they can be swungentirely out of contact with the arch. In that case the seat-bars wouldrest directly 011 the arch and the seat would occupy its lowestposition. Should this be'too low, the rest-blocks are turned to theposition shown in Fig. 7, and the seat can beheld still higher byputting the other bearing-recesses into contact with the arch, as willreadily be seen. So long as the seat is in riding position the beamswill be held under the arched axle in position to be controlled by thefeet of the operator, and the weight of arch-bar S and the adjunctsthereof will be in position to counterbalance his weight. Under thesecircumstances the spring 21. will act as a cushionspring to act againstextreme depression of the beams, the chain and lever may be used toraise the shovels clear of the ground, and

the springs 34 will act as lift-sprin gs or weightneutralizers.

When it is desired to convert the device into a walking-cultivator, theseat-bars are swung forward on their pivots in lugs 25, raising the rearends of bars 29 and forcing the slides rearward until the position shownin Figs. 2 and 4 is reached. Then the seat is out of the way, thearch-bar with the weight incident thereto is brought back close to theaxle of the carrying-frame, and the beams are ex-' tended rearward tothe proper positions to be used while the operator is Walking. Underthese circumstances the chains may be left in their shown conditions andthe cushionsprings be used to counteract extreme downward pressure onthe handles, or they may be loosened to an extent to render them more orless inoperative, or they may be entirely disconnected. The lift-springs34c will be used at all times, and they are particularly desirable onaccount of the even pressure they exert and the facility with whichtheir tension may be regulated. They are put under tension to thedesired extent by means of the bolts and nuts in the heads of the arms,and they are set nearer to or farther from the axis of the pivots of thearms according to the extension it is desired to give them as the beamsare raised and lowered. They are always under tension, the rock of thearms does not vary the tension excessively, the leverage increases asthe tension decreases, and there is no perceptible variation in theaction of the springs on the beams from the beginning to the end of alift. The adjustment of the belts in the heads varies the tension of thespring or the pull that it exerts, while the adjustment of the links inextensions 24" varies the extension of the spring or the distance thatit stretches. One adjustment is complementary of the other and neitherproduces precisely the same effect as the other.

The seat-bars act as levers to extend or contract the frames, and theyare well adapted for that purpose for the reason that the swing thatconverts the device into a walking-cultivator carries the seat out ofthe way, while the reverse movement brings it back again; but it isobvious that a great part of the advantages incident to the extensibleframe can be obtained by using shifting-levers having no connection withthe seat or even by omitting levers altogether.

In Figs. 8 and 9 a suggestion is given of an extensible frame in whichthe axle is connected with the slide, and the arched draftbar isconnected with the an gle-bars that form the hounds of the tongue. Inthat instance the frame is shown in plan in Fig. 8, while Fig. 9 is asection through a modified slide. The

angle-bar 3 bears against an angular surface formed in the bearing-block7", fixed on the axle, and is held in place by a strap 7 which isfastened to the block.

The entire cultivating mechanism, includin g the lifting-lever and theaccessories thereof, are carried on the slides, and so there is nodisa'rrangement of parts when the device is converted from awalking-cultivator to a riding-cultivator, and the reverse.

The lift-spring is applicable to all straddlerow cultivators, and theextension 249 of the brace-bar 24 is merely typical of a relativelyimmovable part of the frame adjacent to the rock-arm.

Having thus described some of the forms in which our invention maybeembodied, we now proceed to concisely point out the features that weclaim as new and desire to protect by Letters Patent, namely 1. In acultivator, the combination of a draft-frame, having carrying-wheels, aslide mounted to move lengthwise of the frame, beams. connected with theslide and beamraising mechanism also connected with the slide.

2. In a cultivator; the combination of a draft-frame, an arched axle forthe draftframe having carrying-wheels, a slide on the frame adapted tomove lengthwise thereof, an arched bar connected with the forward end ofthe slide, beams connected with the arched bar, levers on the rear endof the slide, and chains or the like extending from the levers forward,around bearings on the arch-bar and downward to the beams.

3. In a cultivator, the combination of a frame consisting in part of twoparallel bars lengthwise of the cultivator,an axle connected withcarrying-wheels, a slide on each of the bars, a transverse arch-barconnected with the front ends of the slides, cultivator-beams connectedwith the arch-bar, levers on the rear ends of the slides, chains, or thelike extending from the levers around bearings on the slides andconnecting with the beams, and braces extending from the lower parts ofthe arch-bar and connecting-with the slides in the rear of the axle.

4. In a cultivator the combination of a draft frame havingcarrying-wheels, a slide mounted to move lengthwise on the draft-frame,cultivator-beams connected with the slide and a lever to shift the slideon the draft-frame.

5. In a cultivator, the combination with carrying-wheels andcultivator-beams longitudinally shiftable with relation to the wheels,of horizontally-extending lever-bars to shift the wheels and beams withrelation to each other, and a seat on the extended ends of the levers.

6. In a cultivator the combination of a Wheel-supported frame, a slidelengthwise thereon, cultivator-beams connected with the slide, seat-barspivotally connected with the slide, and links connecting the seat-bars,with the wheel-supported frame.

7. In a cultivator, the combination with the frame'and the axle thereof,of seat-bars pivoted to the frame in front of the axle, and swingablerest-blocks pivoted on the bars and having bearing-recesses at differentdistances from their pivots, which recesses are adapted to engage theaxle.

S. In a cultivator, the combination with the horizontal sleeve of thebeam-coupling, of a vertical arm rigid with the sleeve, and anextensible spring connected at one end with the extended end of the armand at the other end with a relatively immovable part of the cultivatoradjacent to the axis of the sleeve.

9. In a cultivator, the combination with the horizontal sleeve of thebeam-coupling, of a vertical arm rigid with the sleeve, an extensiblespring connecting with the extended end of the arm by means of a boltadjustable lengthwise of the spring, and a set of relatively immovablebearings for the opposite end of the spring near to and at difierentdistances from the axis of the sleeve.

In testimony whereof we sign our names in the presence of twosubscribing witnesses.
